Abstract
Swirling flow with particle deposition effects at the lateral surface is numerically investigated. The flow field calculation results have been obtained as the solutions of the Navier-Stokes equations. Various flow regimes with the formation of axial recirculation zones are presented. The convection-diffusion model is used for the determination of the flow particle concentration and the formation of typical sedimentation zones.
Highlights
Swirling flows have many applications in industrial engineering, in particular, in hydrotechical construction, in gas turbine combustion chambers and in vortex chambers, for the intensification of heat and mass transfer processes [1,2,3,4,5]
The investigated device is modeled as a vertical pipe with a tangential swirler at the bottom
The airflow is moved through the tangential swirler into the pipe by creating a pressure gradient at the top
Summary
Swirling flows have many applications in industrial engineering, in particular, in hydrotechical construction, in gas turbine combustion chambers and in vortex chambers, for the intensification of heat and mass transfer processes [1,2,3,4,5]. A vortex atomizer model which generates aerosol particle flows is discussed. The investigated device is modeled as a vertical pipe with a tangential swirler at the bottom. It is placed at some distance from the horizontal plane with the input powder. The airflow is moved through the tangential swirler into the pipe by creating a pressure gradient at the top. After the intermixing of the two-phase blend, an aerosol flow at the top of the pipe is formed
